This invention provides an oil burner which is adapted tobe manufacturedeconomically, assembled with easeand dispatch, readily separable for anydesired purpose and free from fastenings which corrode and prevent theeasy dismemberment of the parts when, for any cause, it is desired totake the burner apart. v

The invention supplies a burner which 1s capable of general use infurnaces, stoves and heaters, and which comprises a few number of partswhich are accessible with the greatest.

facility for cleaning, replacement or other purpose. lo' While thedrawing illustrates a preferred embodiment of the invention, it is to beunderstood that in adapting' the means to meet specific needs andrequirements, the deslgn may be varied and changes in the mlnorde- 2otails of construction may be resorted to wlthin the scope of theinvention as claimed, with out departing from the spirit thereof.

For a full understanding of the invention and themerits thereof,reference is to be had to the following description and the drawinghereto attached, in which,-

Figure 1 is a top plan view of an oil burner embodying the invention,one-half of the spreader being broken away to'show the relation of theparts more clearly.

Figure 2 is a vertical, central sectional view of the burner.

Figure 3 is a perspective view of the annular delector and oil catcher.

Corresponding and like arts are referred to in the following descrlptionand designated in the several views ofthe drawing by like referencecharacters.

The burner comprises a base which is hollow and of circular outline.This base preferably consists of a casting and includes an outer wall 1,a to 2, an inner wall comprising inclined portions 3 and 4, and an innerflange 5 at the bottom edge of the inner wall.

The top portion 3 of the inner wall flares t'o effect a spreading of theHaine. The bottom portionk 4 ofthe inner wall tapers slightly.

The annular delector and oil catcher includes 'an outer wall 6 and aninner wall 7 These close a space which is of rounded outline at thebottom, as Shown most clearly in Figure 2 of the drawing. A drain pipe 8connects with an opening 9 formed in the bottom of the deflector tocarry off surplus oil. The outer wall 6 is of greater height than theinner wall 7 and conforms to the taper of the portion 4 of the innerwall of the base, and upon the outer surface of the wall 6 are verticalribs 10 engaging vertical grooves in the 6o portion 4 whereby turning ofthe deflector and twisting of the pipe 8 is avoided.

The burner tip 11 consists of a plug provided upon its bottom side withlugs 12 which are stepped upon the bottom side to o5 provide inner andouter portions toproperly center and support the tip. The outer portionsof the lugs 12 rest upon the inner wall 1 7 of the annular deflector.The inner portions of the lugs 12 extend into the space 70 surrounded bythe inner wall 7 and serve to properly position the tip. A verticalopening is formed centrally of the tip 11 and receives a pipe 13 whichis threaded therein.' The topv side of the tip 11 slopes outwardly anddown- 7 wardly in all directions, and is formed with a plurality ofradially disposed grooves 14 whichv constitute passages for the flow ofthe gas. The grooves or passages 14 communicate with the upper end ofthe pipe 13. The

spreader 15 has its outer peripheral portion :flared to conform to theflared portion 3 of the inner wall of the base. The annular space 16formed between theviared portions of the spreader 15 and thebase,constitute 8,5. Y

a flame outlet which in the operation ofthe burner effects a. spreadingof the ame so as to reach the side walls of the lire box or like part inwhich the burner may be located.

A depression is formed centrally within the bottom side of the spreader15 to snugly receive the burner tip 11'. The space 17 formed between theadjacent walls of the burner tip and the recess of the spreader in whichthe burner tip is fitted iiares downwardly and results in the formationof ,an annular outlet for the vapors flowing through the passages 14,thereby resulting in the production ofV an annular flame, which, afterimpinging upon the inner wall 7 of the annular deflector is 10 'hasdirected upwardly and outwardly through the liame outlet 16. Lugs 18depend from the. bottom side of the spreader 15 and are stepped similarto the lu s 12 to engage the outer `wall 6 of the de ector and supportand center the spreader. A ,lug 19 pro]ects upwardly from the spreaderand is disposed centrally thereof and is apertured to receive a suitableinstrument for lifting the spreader when required. A vaporizing orgenerating coil 2O is located within the space of the base and conformsto the bottom portion 4 of the inner wall thereof. The lower end of thecoil 20 connects with thepipe 13 and the upper end lconnects with a.supply pipe 21 leading from a tank, not shown, or other source of oilsupply. This arrangement results in housing the coil 20 and preventingthe chilling thereof when the burner is in operation.

The burner is primed by supplying a small -quantity of oil to thereceptacle formed between the walls 6 and 7 of the annular deflector oroil catcher. Spaced webs 22 located at thev sides of the opening 9prevent escape of the oil through said opening and drain pipe 8. The oilin the receptacle being ignited lburns and heats the parts sufficientlyto vaporize the oil flowing through the coil 20. The gas thus producedpasses through the pipe 13 and ducts 14 to the outlet 17 where it islighted, the resulting flame being de- 'flected upwardly and outwardlythrough the space 16. The tops of the webs 22 are lower than the top ofthe wall 7 and any oil accumulating in the catcher passes 0E through theoutlet 9 and drain pipe 8 to the determin nate point of discharge. It isobserved that no -fastenings are employed for connecting vthe arts,hence the burner may be easilyand quic ly assembled and separated withthe greatest facility, as occasion may require. The burner tip 11 has aiange surrounding I the opening formed therein in which the pipe 13 isfitted., The grooves 14. are formed in Vthis flange. The surfaceexterior to the iange is unfinished to provide for a flow of the oil bypreventing a close t between the adjacent surfaces of the parts 11 and15.,

Having thus described the invention, we

claim 1. A hydrocarbon burner including a hollow baseand having theinner wall comprising an upper iared portion and a lower taperingportlon, a Vaporizing-coil disposed within the space of the base andlying close to the lower tapering portion of the said inner passagesformed between adjacent sides of the tip and spreader which communicatewith a flame outlet opposite the space formed between the inner andouter walls of the deflector.

3. A hydrocarbon burner comprising a hollow base including inner andouter walls, the inner wall having its upper ortion flared and its lowerportionv tapere .an annular deflector and oil catcher supported within'i the lower tapered/portion of the inner wall l ot'the base, a burnertip mounted upon the inner wall of the deflector, a spreader mountedupon the outer wall ofthe deflector and having its outer side flared4and spaced from the inner ared portion of the base,` and a vaporizingcoil within the base and disposed close against the tapered portion ofthe inner wall thereof.
